Dental prosthesis

A single-part or multi-part dental prosthesis blank, said blank comprising

• a gum-colored material (14) and a tooth-colored material (12),
• wherein an occlusion plane extends at a side of the tooth-colored material opposite to the gum-colored material, which gum-colored and tooth-colored materials (12, 14) are bonded together by adhesion, polymerization, injection molding and/or by integrally producing,
• wherein a boundary (16) between the gum-colored and tooth-colored materials, as viewed following a course of a dental arch, are wave-shaped with alternating grooves and ribs (22, 24) forming troughs and crests, and are radially formed in an anterior region of the dental arch, as viewed in an oral vestibular direction,
• wherein the boundary (16) between the tooth-colored and the gum-colored material (12, 14) as viewed from a distal to mesial direction across the course of the dental arch rises in waves towards an occlusal plane, with an average inclination of 15 degrees or more, and
• wherein the tooth-colored material (12), in a molar region (30), has a greater height in the gingival-occlusal direction than in an anterior tooth region (32).
